Has anyone ever heard/seen Egyptian walking onions? They are the only spring onion that form "sets" on top that you can plant and also are perennial and super easy to grow. I had them at my old house and can't find them anywhere now. The only way to get them is to find someone who has them. I am really missing those onions (as they would be producing in abundance right now in early spring) and thought maybe someone knows of them and can get them? Thanks for any info!
